I love espionage RPGs and am always looking for different systems to try. When I heard about Classified it was labeled a Victory Games James Bond RPG clone, and basically it is. I played thee original many times in the 80s and 90s, so I have a bit of experience with similiar game mechanics. That said, it does a much better job of explaining rules and presenting game concepts. This game compared to other espionage RPGs is better run with one or two players maximum. The different levels of success is a great mechanic, something that 7th edition Call of Chtulhu is doing. Skills are a bit clunky, but once you play a couple sessions you get accustomed to it.
Is it great? No, but its good and playable.
